Description

Verfahren zur Beseitigung der Drehfeldabhängigkeit von Drehstromzählern Beim Verfahren zur Beseitigung der Drehfeldabhängigkeit von Drehstromzählern nach dem Hauptpatent, bei welchem höchstens zwei diametral angeordnete Triebsysteme auf eine gemeinsame Scheibe wirken, wird dem Magnetfeld mindestens eines Triebsystems eine Feldkomponente aufgedrückt, die in ihrer Größe und Phase von dem Magnetfeld einer der übrigen Spannungsspulen abhängt. Das wird bei Drehstromzählern mit drei Triebsystemen, die auf zwei Scheiben wirken, praktisch dadurch erreicht, daß mindestens eine Spannungsspule oder eine von ihr induzierte Hilfsspule mit zwei auf j e einem Spannungseisen der übrigen Triebsysteme angeordneten Hilfsspulen in Reihe geschaltet ist.Procedure for eliminating the rotating field dependency of three-phase electricity meters In the procedure for eliminating the rotating field dependency of three-phase electricity meters according to the main patent, in which at most two drive systems arranged diametrically a common disc act, the magnetic field of at least one drive system a field component is imposed, which in its size and phase of the magnetic field depends on one of the remaining voltage coils. With three-phase meters, this is three Drive systems that act on two discs, achieved in that at least a voltage coil or an auxiliary coil induced by it with two on each one Voltage iron of the other drive systems arranged auxiliary coils connected in series is.

Die Erfindung betrifft eine weitere Ausgestaltung des Verfahrens nach dem Hauptpatent mit drei Triebsystemen, die auf zwei Scheiben wirken, und zwar sind die Wicklungsanfänge der beiden diametral gegenüberliegenden Spannungsspulen und der dritten Spannungsspule an die Phasen RS und T angeschlossen und die Wicklungsenden der beiden diametral gegenüberliegenden Spannungsspulen mit dem Wicklungsende einer als Wicklungsfortsatz zur dritten Spannungsspule auf dem Spannungseisen dieser Spule aufgebrachten Hilfsspule zu einem Sternpunkt vereinigt, so daß in der Hilfsspule eine zusätzliche Spannung erzeugt wird, deren Vektor in Phase mit demVektor der dritten Spannungsspule ist und der gleich der Verschiebung des Sternpunktes gegen den Nullpunkt ist.The invention relates to a further embodiment of the method according to the main patent with three drive systems that act on two discs, namely are the winding starts of the two diametrically opposite voltage coils and of the third voltage coil connected to phases RS and T and the winding ends of the two diametrically opposite voltage coils with the winding end of one as a winding extension to the third tension coil on the tension iron of this coil Applied auxiliary coil combined into a star point, so that in the auxiliary coil an additional voltage is generated, the vector of which is in phase with the vector of the third voltage coil and which is equal to the displacement of the neutral point against is the zero point.

Ein Ausführungsbeispiel ist in der Abb. i dargestellt. Die beiden Triebsysteme mit den Spannungsspulen i und 3 liegen sich auf der einen Scheibe diametral gegenüber, während das dritte Triebsystem mit der Spannungsspule 2, welches um go ° gegen die Triebsysteme mit den Spannungsspulen i und 3 versetzt ist, auf die zweite Scheibe arbeitet. Eines der beiden diametralen Triebsysteme ist umgepolt. Die Anfänge der beiden diametralen Spannungsspulen i und 3 liegen an den Phasen RT, der Anfang der Spannungsspule 2 an der Phase S. Nun sind die Enden der drei Spannungsspulen nicht an den Nullpunkt geführt, sondern an einen Punkt M, der das Wicklungsende einer Hilfsspule q. der Spannungsspule 2 bildet. Diese Hilfsspule q. ist als Wicklungsfortsatz der Spannungsspule 2 auf dem Spannungseisen dieser Spannungsspule aufgebracht. Aus dem vektoriellen Wicklungsschemalder Abb. 2 ist@zu ersehen, daß die Wicklungsenden der beiden diametral gegenüberliegenden Spannungsspulen mit dem Wicklungsende der Hilfsspule 4 zu dem Sternpunkt M vereinigt sind. In der Hilfsspule wird eine Zusatzspannung 0M induziert, die in Phase mit der Spannung SO der Spule z ist und sich mit den Spannungen R0 und TO zu den Spannungen RM und TM der Spulen T und 3 zusammensetzt. Es wird also durch die Einführung der Zusatzspannung der Hilfsspule eine Verschiebung des Sternpunktes vom Nullpunkt und damit eine Verschiebung der Lage der Spannungsvektoren der Spannungsspulen z und 3 herbeigeführt und dadurch der bei Drehstromzählern auftretende Phasenfehler beseitigt.An embodiment is shown in Fig. I. The two drive systems with voltage coils i and 3 are diametrically opposed to one another on one disk, while the third drive system with voltage coil 2, which is offset by go ° from the drive systems with voltage coils i and 3, works on the second disk. One of the two diametrical drive systems is polarized. The beginnings of the two diametrical voltage coils i and 3 are at the phases RT, the beginning of the voltage coil 2 at the phase S. Now the ends of the three voltage coils are not led to the zero point, but to a point M, which is the winding end of an auxiliary coil q . the voltage coil 2 forms. This auxiliary coil q. is applied as a winding extension of the tension coil 2 on the tension iron of this tension coil. From the vectorial winding diagram Fig. 2 it can be seen that the winding ends of the two diametrically opposite voltage coils are combined with the winding end of the auxiliary coil 4 to form the star point M. An additional voltage 0M is induced in the auxiliary coil, which is in phase with the voltage SO of the coil z and is composed of the voltages R0 and TO to form the voltages RM and TM of the coils T and 3. Thus, by introducing the additional voltage of the auxiliary coil, a shift of the star point from the zero point and thus a shift in the position of the voltage vectors of the voltage coils z and 3 is brought about and the phase errors that occur in three-phase meters are eliminated.

Der Zähler ist, trotzdem er nicht an den Phasenspannungen R0, SO und TO angeschlossen ist, vom Spannungsdreieck unabhängig, da die falsche Lage der Spannungen durch das Zusammenarbeiten des Stromflusses bzw. des Stromes je eines Meßwerkes mit dem Spannungsfluß bzw. der Spannung des anderen Meßwerkes kompensiert wird.Despite not being connected to the phase voltages R0, SO and TO , the meter is independent of the voltage triangle, since the wrong position of the voltages is caused by the cooperation of the current flow or the current of one measuring mechanism with the voltage flow or the voltage of the other measuring mechanism is compensated.
